This solves the following oops:

Which patch broke this? Adding a Fixes: line will help us figure
out where to backport this.
The issue has been around since the legacy clock data code already, I am
not quite sure which initially broke it though. As such, we can use the
initial clock conversion commit as a fixes by for this:
commit aafd900cab87d339dc3004c241eebc854005124b
Author: Tero Kristo <t-kristo@xxxxxx>

CLK: TI: add omap3 clock init file
I'll add a fixes tag to this and queue it for 4.3-rc-fixes.
